Abstract: La0.9Sr0.1Ga0.8Mg0.2O3-d (LSGM) electrolyte materials were synthesized using solid state reactions. The LSGM material film was deposited by radiofrequency magnetic sputtering on La0.7Sr0.3Cr0.5Mn0.5O3-d (LSCM) substrates. The analysis results show the films did not form but formed some “mountains” when deposited for 4 h. While the depositing time extended to 12 h, a dense and uniform film with perovskite phase was obtained, and the element amounts of the film were closed to those of the LSGM materials.

Abstract: Perovskite-structure La0.7Sr0.3Cr0.5Mn0.5O3-δanode powder was prepared by glycine nitrate process. The result of characterization indicated that the pore morphology and mechanical property of anode support pellets using starch as pore-forming agent are superior to that of using activated carbon. The maximum value of porosity and specific surface area are 40%, 1.256m2/mg at 10MPa, respectively. The conductive mechanism is small-polaron conductive mechanism at low temperature, but it is metalloid conductive mechanism at high temperature.
